The “Graph Annotation Framework” (GrAF) defines an API and an XML format to store and query linguistic annotations as annotation graphs. The format was standardized as ISO 24612 in 20121, and was explicitly developed as an underlying data model for linguistic annotations in a radical stand-off approach2 ([Ide and Suderman 2007]). The basic data structures are annotation graphs as proposed in [Bird and Liberman 2001], and are general and expressive enough to encode all known varieties of annotation in linguistics and other “annotation-based” disciplines. Although GrAF is not a TEI-compatible format, both standards share a certain technological foundation and grew in a similar ecosystem, but with slightly different applications in mind. In our talk we will show the connections between TEI and GrAF, propose an option to convert between the „two worlds“, and demonstrate a query system for GrAF data that we already use in typological analysis of annotated data from language documentation projects.
